I doubt Orochimaru will die. Orochimaru will probably conquer Konoha and claims himself as Hokage (didn't he got mad not becoming the Fourth?). Sasuke will have to seek him. I doubt they gonna end everything here.

I also love how Naruto save Sasuke. Perhaps this time, Sasuke will see the Nine-tail's Chakra unless he pass out again. (With Haku: Sasuke passed out; with Orochimaru: Naruto gets another seal)
